To alt whom it may concern i Be it known that I, RICHARD HERBERTPARFITT, a subject of the King of Great Britain, residing at VictorialVorks, Tunnel avenue, East Greenwich, in the county of Kent, England,have invented certain new and useful Improvements in Pattern-Cylindersor the like for Use in Connection with the Manufacture of InlaidLinoleum or other Similar Material, of which the following is aspecification.

In the manufacture of inlaid linoleum the various iigures that form thepattern are cut out of colored sheets and are assembled upon a backingof canvas. For effecting this purpose it is customar to employ one orother of two kinds of cy inders which are respectively known as positivepattern cylinders and universal' pattern cylinders both of whichcomprise a number of xed knives, operatinov in conjunction with movablepusher plates that occupy the spaces bounded by the knives. In thepositive pattern cylinders these knives are irregularly formed andspaced in accordance with the particular pattern to be produced, and inthe event of the pattern comprising a number of colors, a separatepattern cylinder provided with a different arrangement of knives isrequire for each color. These pattern cylinders constitute a set, andone set of positive pattern cylinders is capable of producing one designonly. The cut material that is not transferred from any one cylinder tothe backing is termed waste and is returned to suitable machinery bywhich it is again transformed into the aforesaid sheets. In theuniversal pattern cylinders the knives are regularly formed and spaced,the spaces bounded by the knives, whether of rectangular, triangular,hexagonal, or other formation comprising units of equal shapes andsizes. In this arrangement all the pattern cylinders in a set are thesame, and one set of universal pattern cylinders is capable of producinga number of diiferent designs, the constituent parts of which are madeup of varying multiples of the aforesaid units.

The present invention has for its chief object to enable a number ofdesigns, which would hitherto have required a set of positive patterncylinders for each design, to be produced from one set of patterncylinders.

According to this invention each cylinder (or equivalent knife carryingdevice) of a set 'of attern cylinders is built up of (l) similar yarranged groups of knives of a desired pattern formin a complete designof the type hitherto confined to positive pattern cylinders, each grouphaving individual knives adapted to cut complete gures of irregularform, and of (2) short subsidiary knives crossing and connectingtogether the groups of primary knives and mainly occucupyinglthe spacewhich in positive cylinders giving a corresponding design is occupiedby'the ground of the design,the subsidiary knives being so grouped as toenable (by proper selection of the sections cut out) a great number ofdifferent designs based on the primary design of the main knives to beobtained from the same set of cylinders. Each of such designs wouldhitherto have required a separate set of cylinders. The selection of thesections cut by the knives is effected byV any known form of picking outdevice, such as a picking out roller with pusher pins, the designobtained from the cylinders depending upon the arrangement of such pinsupon the rollers. The adjacent sections cut from the same sheet ifselected, as part of the particular design in process of formation, arejoined upon the canvas backing and after the usual pressing operationshow no signs of the original division. Any number of pieces of whatevershape that are contiguous to one another can be cut out from one sheetand assembled on a canvas backing as one whole figure.

It is to be understood that it is not desired to limit the invention tocylinders as it is equally applicable to plates, presses or the likethat could fulful the functions of a cyliiider.

My invention is illustrated in the accompanying drawings, in which thefull lines indicated in Figures 1, 2, 3 and l represent four differentarrangements of knives which together constitute a set of positivepattern knives. Fig.V 5 shows a four color design which may be producedby the pattern knives of the preceding iigures. Fig. 6 illustrates a setof knives arranged in accordance with this invention for producing notonly the design illustrated in Fig. '5 but additional designs suoli forexample as those which are illustrated in Figs. 7, 8 and 9. Fig. 10shows in diagrammatic form the general arrangement of a cylinder machinefor making four color linoleuin.

Referring first te the known arrangement shown in Figs. l, 2, 3 and 4the knives indicated in Fig. l cut out the shaded portions marked A froma sheet of material which may for example be red, the portions so cutout being transferred to the canvas backing by the usual pusher pins orother devices ordinarily employed.

The unshaded portions B represent the waste material hereinbeforereferred to that is transferred to another machine for remaking intosheets. This material is cut up into suitable sizes for handling, byknives indicated by the dotted lines C which however form no part of thepattern producing knives.

The knives indicated in Figs. 2, 3 and 4 cut out the shaded portionsmarked A, A2, A3 from sheets of material which may for example be blue,green and yellow respectively, the material so cut being transferred tothe backing and producing the design indicated in Fig. 5, the unshadedportions B in each figure representing the waste and the dotted lines Cindicating the knives for cutting up the same. In the arrangement abovedescribed the cylinders, plates, presses or the like that carry theaforesaid knives are not interchangeable and the original form of thedesign can not be altered, and although each arrangement of knives shownin Figs. l, 2, 3 and 4 virtually constitutes a different design, noindividual design can be utilized owing to the fact that the knives onthe remaining cylinders, 'plates or the like, are incapable of cuttingout pieces to replace the waste that would be discarded from suchdesign.

According to this invention in order to produce a design such as thatwhich is illustrated in Fig. 5 each of the four cylinders, plates,presses or the like is provided with an arrangement of knives similar tothat indicated in Fig. 6, the full lines representing the knives thatproduce the design sho-wn in Fig. 5 and the dotted lines indicatingknives that are inserted in ea-ch cylinder, plate 0r the like forproducing additional designs a few o-f which are illustrated in Figs. 7,8 and 9. The main knives in the illustration shown are divided into twochief groups, D and D2, the former group constituting a set of starshaped cells of somewhat complicated pattern, while the group D2consists of stars inclosed in the said cells. The ground between the twochief groups is occupied by the short connecting knives D3 shown indotted lines. Fig. 6 shows a single knife segment, which is usually castin one piece and curved to the shape of the knife cylinder, to which itis screwed through any of the convenient spaces between the knives, thelonger spaces being generally chosen. ift will thus be seen that owingto the various shapes and arrangements of knives being repeated in eachcylinder, plate or the like, any piece of material ejected from any onecylinder can be replaced by a corresponding piece of material from anyof the remaining cylinders, consequently it is possible to eject or toretain any part of an original pattern or to add thereto. The additionalknives represented by the dotted lines being all adaptable for producingother designs in addition to serving for cutting up waste.

rPhe cylinder apparatus shown diagrammatically in Fig. 10 illustratesthe manner in which this invention may be practically carried intoeffect. The large central drum E is the one over which passes thebacking receiving the colored material and carrying it to the usualpressing apparatus. rlfhe four bands F of different colored linoleumsubstance are carried over the cylinders G arranged at one side of thecentral drum E. For convenience of illustration the four bands are shownof different thickness to indicate the different colors and the way inwhich the cut pieces f fit between each other on the drum E. Between thecylinders G and drum E are situated the knife cylinders H, the lower oneof which is shown in section to illustrate a method of selecting andejecting the pieces cut by the knives D. Each of the cylinders Greceives a set of knife segments all of the same design, as for instancethe segment shown in Fig. 6, so that the complete cylinders are allalike as regards knife pattern. The knives D cut up the band F ofcolored composition into design units at the point of contact betweenthe cylinders G and H.

Within each cylinder is an ejecting roller J with studs j which meetcertain of the ejecting pins K by which the pieces f of coloredcomposition cut by the knives D are ejected and drop into the wastereceptacle L. The studs on the roller J are grouped so as to select aswaste those pieces which do not enter into the design, the remainingpieces being ejected on to the backing on the central drum E by means ofthe smooth roller J which presses out all the pins K left untouched bythe studs j. The action in all the knife cylinders is the same, but thero-llers J are made so that the design units of the various coloredmaterials are complementary and fit into place on the drum E as the drumand cylinders revolve, in the manner shown diagrammatically in thedrawing. By varying the stud arrangement of the rollers J, with similarknife patterns (such for eX- ample as are illustrated in Fig. 6) on eachknife cylinder a great variety of designs can be produced without anyfurther alteration. These four examples given in Figs. 5, 7, 8 and 9 areonly a few out of seve hundred which could be prepared from the knifevarrangement of Fig. 6, when repeated on each of the knife cylinders.

W'hat I claim and desire to secure by Letters Patent of the UnitedStates is In a linoleum machine, a plurality of knife carriers eachhaving thereon a lplurality of groups of main knives arranged to cutpatterns of complex multi-point design, and a set of subsidiary designcutting knives connecting together said groups of main knives, theknives of each carrier being like those of all others in design, and anadjust- 10 able selective ejecting mechanism for each carrier.
